Fast MCA board with Cortex M4 microprocessor for amateur portable Gamma Spectrometry project released. The MCA can work as a robust Gamma Spectrometer and as a Scintillation Counter Survey Meter with NaI(Tl) probe.
If you need electronic only module excluding enclosure and battery, please check for SKU RH-MCA-4-Module here -> link
Contact me to get the HEX file firmware for your device! You'll need pickit programmer to upload the firmware.
MCA Terminal is freeware with open communication protocol.
Published for downloading. You'll need pickit programmer to upload the firmware.
What is new in 1.06:
- Added UART mode for live spectrum upload
- Added new file format for SD logs, it allows faster data dump
- Fixed melody promt bug after SD file saving
Added link to download Spectrum Utility Windows software for the MCA ver.1
Posted testing result for channels drift vs temperature changes for SiPM sensor. Added hardware correction to the silicon photomultiplier board prototype.
Summarize the technical specifications and differences between all existing editions of the MCA module boards and contain video about the beta ver.3 for sloped handheld enclosure.
MicroFC-60035-SMT manufactured by Sensl is 6x6mm SiPM silicone photomultiplier sensor. The C series 60035 has P-on-N type structure and used for blue range light, that's why it fit perfectly CsI(Tl) scintillation crystal. The circuit works as an amateur gamma spectroscopy detector for 192kHz audio card MCA.

Any previous customer's data not migrated from the old website, that's why you are welcome to register with a new account. If you need any information regarding your open orders dated before 29 by August 2018 please contact us.
The page was created in attempt to help users to understand and set the main settings of the BecqMoni MCA program. I'll add the further links to PDF files with instructions. All these documents are prepared in my freetime and it represent only my personal experience. You are welcome to contribute.
Article describing work-log process of assembling portable battery operated MCA with NaI(Tl) detector. The device has good linearity and FWHM% resolution less than 8%. The circuit evolves high voltage for a photomultiplier tube, it has analog electronics to process pulse shape and it has digital electronics to count pulses and analyze spectra.
Любительской гамма спектрометрией я увлекся в начале 2015, когда измерять уровень радиации обычным дозиметром стало уже не интересно и захотелось заглянуть поглубже чтоже там на самом деле происходит. Сразу оговорюсь, что представленный в статье прибор не является профессиональным лабораторным гамма-спектрометром так как имеются некоторые ограничения. Но, несмотря на это, с помощью такой приставки можно легко определять радионуклиды излучающие гамму в пределах 13кеВ-1700кеВ.
The receiver is a simple superheterodyne type with quartz crystal filter. The circuit is based on two NE612 mixer IC’s and one audio amplifier LM386. The electrical circuit as it described below in the manual is intended for 14.000MHz – 14.350MHz upper single side band receiving of amateur radio transmissions. It has compatibility with AD9850 DDS and active loop antenna.
As you know, PIN diode can be used for detection of gamma radiation. Maxim Integrated announced a good materials for the experimental building of such type detector. Here you can find my implementation, including oscilloscope screenshots and short video.
